About this deck
For most of history, "elements" meant earth, water, fire, air. The chemical revolution gave that scheme a final shove — and three thinkers laid the groundwork. Key sections include: THE PERIODIC TABLE /; Before the table: scattered clues; Mendeleev arranges the elements; The gaps filled themselves; Moseley fixes the order: atomic number; Periods and groups: rows and columns mean things; Reading an element tile; The colored families of matter; The bottom drawers: f-block exiles; The transuranics: elements made by hand.
